The springs, called Kuruvungna , were used as a fresh water source by the Tongva people since 400 B.C.E., and continue to produce 22,000 - 25,000 gallons of water a day.[2] The springs are also sometimes referred to as the Gabrieleno Tongva Springs, the Tongva Holy Springs, and the Sacred Springs. The springs have a UCLA Archaeological designation of CA-LAN-382.
